## Description
- Add `context.Context` to Privval interface
This pr does not introduce context into our custom privval connection protocol because this will be removed in the next release. When this pr is released.
Missed setting the buffer size on the subscription. Note, this doesn't really "fix" this test (a la ref: https://github.com/tendermint/tendermint/pull/5710).
However, I spent a good chunk of time looking at this test with many logs and I'm pretty sure this is mainly due to the fact that none of the nodes get the conflicting vote in time.
closes: #6127
Executed a local network using simapp and looked for logs that seemed superfluous. This isn't by any means an exhaustive grooming, but should drastically help legibility of logs.
ref: #5912
Conflicting votes are now sent to the evidence pool to form duplicate vote evidence only once
the height of the evidence is finished and the time of the block finalised.
blockchain/vX reactor priority was decreased because during the normal operation
(i.e. when the node is not fast syncing) blockchain priority can't be
the same as consensus reactor priority. Otherwise, it's theoretically possible to
slow down consensus by constantly requesting blocks from the node.
NOTE: ideally blockchain/vX reactor priority would be dynamic. e.g. when
the node is fast syncing, the priority is 10 (max), but when it's done
fast syncing - the priority gets decreased to 5 (only to serve blocks
for other nodes). But it's not possible now, therefore I decided to
focus on the normal operation (priority = 5).
evidence and consensus critical messages are more important than
the mempool ones, hence priorities are bumped by 1 (from 5 to 6).
statesync reactor priority was changed from 1 to 5 to be the same as
blockchain/vX priority.

time_iota_ms is intended to ensure that an honest validator always generates timestamps
with time increasing monotonically. For this purpose, it always suffices to have this parameter
set to `1ms`. Allowing users to choose different numbers increases bug surface area.
Thus the code now ignores the user provided time_iota_ms parameter (marking it as unused),
and uses 1ms internally.
This implements a new `Transport` interface and related types for the P2P refactor in #5670. Previously, `conn.MConnection` was very tightly coupled to the `Peer` implementation -- in order to allow alternative non-multiplexed transports (e.g. QUIC), MConnection has now been moved below the `Transport` interface, as `MConnTransport`, and decoupled from the peer. Since the `p2p` package is not covered by our Go API stability, this is not considered a breaking change, and not listed in the changelog.
The initial approach was to implement the new interface in its final form (which also involved possible protocol changes, see https://github.com/tendermint/spec/pull/227). However, it turned out that this would require a large amount of changes to existing P2P code because of the previous tight coupling between `Peer` and `MConnection` and the reliance on subtleties in the MConnection behavior. Instead, I have broadened the `Transport` interface to expose much of the existing MConnection interface, preserved much of the existing MConnection logic and behavior in the transport implementation, and tried to make as few changes to the rest of the P2P stack as possible. We will instead reduce this interface gradually as we refactor other parts of the P2P stack.
The low-level transport code and protocol (e.g. MConnection, SecretConnection and so on) has not been significantly changed, and refactoring this is not a priority until we come up with a plan for QUIC adoption, as we may end up discarding the MConnection code entirely.
There are no tests of the new `MConnTransport`, as this code is likely to evolve as we proceed with the P2P refactor, but tests should be added before a final release. The E2E tests are sufficient for basic validation in the meanwhile.
After a reactor has failed to parse an incoming message, it shouldn't output the "bad" data into the logs, as that data is unfiltered and could have anything in it. (We also don't think this information is helpful to have in the logs anyways.)
Replace testing.T.Cleanup() with deferred function
calls in test helpers as those cleanup functions
need to be called once the helper returns and not
when the entire test ends.
This reverts a few of the changes introduced in #5723.
Thanks: @erikgrinaker for pointing this out.

`abci.Client`:
- Sync and Async methods now accept a context for cancellation
* grpc client uses context to cancel both Sync and Async requests
* local client ignores context parameter
* socket client uses context to cancel Sync requests and to drop Async requests before sending them if context was cancelled prior to that
- Async methods return an error
* socket client returns an error immediately if queue is full for Async requests
* local client always returns nil error
* grpc client returns an error if context was cancelled before we got response or the receiving queue had a space for response (do not confuse with the sending queue from the socket client)
- specify clients semantics in [doc.go](https://raw.githubusercontent.com/tendermint/tendermint/27112fffa62276bc016d56741f686f0f77931748/abci/client/doc.go)
`mempool.TxInfo`
- add optional `Context` to `TxInfo`, which can be used to cancel `CheckTx` request
Closes#5190
Replace defer with t.Cleanup().
Replace the combination of ioutil.TempDir, error checking
and defer os.RemoveAll() with Go testing.T's new TempDir()
helper.
Mark auxiliary functions as test helpers.
This fixes spurious `TestByzantinePrevoteEquivocation` failures by extending the block range and time spent waiting for evidence. I've seen many runs where the evidence isn't committed until e.g. height 27. Haven't looked into _why_ this happens, but as long as the evidence is committed eventually and the test doesn't spuriously fail I'm (mostly) happy. WDYT @cmwaters?
